This course addresses the following question: how to extract meaningful information from images and video? This is a key question in many contexts for example when we wish to equip a robot with sensing capabilities, when we wish to learn 3D models from multiple images, when we want to search for similar images in a large database or when we wish to perform the analysis of medical images to detect abnormal tissues. Some of these problems are discussed in the course e.g., image enhancement,... Topic: image processing

Visual features like mouth & head pose which are typically characterizing the distraction of... Topics: Image Capturing, Digital Image Processing, Distraction Detection
Most of industries and bridges around us make use of iron for manufacturing their products. On the other hand corrosion is a natural process that deteriorates the integrity of iron surface. Therefore, rusting of iron takes place. To avoid unwanted accidents in industries and bridges, it is necessary to detect rusting in earlier stage, so that it can be prevented. Digital image processing for the detection of the rusting provides fast, accurate and objectives results. In this research paper, we... Topics: Rust detection, Visual Inspection, Image processing
In this paper a novel filtering design intended forthe impulsive noise removal in color images is presented.The described scheme utilizes the rank weighted cumulateddistances between the pixels belonging to the local filteringwindow.

Edge detection is an important first step operation of obtaining information from an image. In this paper, a new edge detection operator is proposed, which is based on the principle of evaluating the local fluctuation of pixel values. The pixel values within a mask are normalized so that they can be treated as probabilities. Then, modified Tsallis entropy of the probabilities is calculated. Edges are detected where the value of this entropy is below a properly chosen threshold. The obtained... Topics: Image processing, edge detection, operator, Tsallis

Image compression is a process to remove the redundant information from the image so that only essential information can be stored to reduce the storage size, transmission bandwidth and transmission time. Recently the JPEG committee has released its new image coding standard, JPEG-2000, which has been based upon DWT. The essential information is extracted by various transforms techniques such that it can be reconstructed without losing quality and information of the image. In this paper a...

In this paper, the segmentation of data in 2D and 3D by texture analysis using Fourier domain filtering is processed. The textural measurements are extracted from the Fourier domain of the data via sub-band filtering. Measurements are extracted by using a novel Bhattacharya- distance and a compact feature space is produced. Each dimension of the feature space is used to form the Quad tree. The classification is performed over the higher level of the tree using fractal measures and is projected... Topics: Filtering, Texture Segmentation, Multi- resolution, Digital Image Processing.
